 Posted: Tue Mar 28, 2006 3:06 am Post subject: how do I remove html from a string? |
 |
|
Hi all, not sure if I'm asking the right wuestion so let me explain what I want to do. I'm developing a theme for Serendipity blog. An entry can contain html, for example a link or an image. What I want to do is truncate the entry body to just 60 or 70 characters, and "truncate:60" or similar works well for me, but when the entry contains any html it gets counted. Does anyone know how I could parse the string/variable and have Smarty remove or ignore any html that begins <img... or <a href...
Cheers

Try this plugin I have found some where on web
<?php
/**
* Smarty plugin
* package Smarty
* subpackage plugins
*/
/**
* Smarty strip_tags modifier plugin
*
* Type: modifier
* Name: strip_tags
* Purpose: strip html tags from text
* strip_tags (Smarty online manual)
*
* @author Monte Ohrt <monte at ohrt dot com>
* @author Jordon Mears <jordoncm at gmail dot com>
*
* @version 2.0
*
* @param string
* @param boolean optional
* @param string optional
* @return string
*/
function smarty_modifier_strip_tags($string) {
switch(func_num_args()) {
case 1:
$replace_with_space = true;
break;
case 2:
$arg = func_get_arg(1);
if($arg === 1 || $arg === true || $arg === '1' || $arg === 'true') {
// for full legacy support || $arg === 'false' should be included
$replace_with_space = true;
$allowable_tags = '';
} elseif($arg === 0 || $arg === false || $arg === '0' || $arg === 'false') {
// for full legacy support || $arg === 'false' should be removed
$replace_with_space = false;
$allowable_tags = '';
} else {
$replace_with_space = true;
$allowable_tags = $arg;
}
break;
case 3:
$replace_with_space = func_get_arg(1);
$allowable_tags = func_get_arg(2);
break;
}
if($replace_with_space) {
$string = preg_replace('!(<[^>]*?>)!', '$1 ', $string);
}
$string = strip_tags($string, $allowable_tags);
if($replace_with_space) {
$string = preg_replace('!(<[^>]*?>) !', '$1', $string);
}
return $string;
}
/* vim: set expandtab: */
?>
